The UGREEN X688 Uno 100W 4-Port GaN Fast Charger combines powerful charging performance, multiple ports, and UGREEN’s distinctive Uno design in one compact charger. It is designed for users who regularly charge several devices and want to reduce the number of separate adapters required at home, in the office, or while travelling.

With a maximum charging capacity of up to 100W, the X688 can provide enough power for many compatible USB-C laptops. At the same time, its four-port configuration makes it convenient for charging smartphones, tablets, power banks, earbuds, and other everyday electronics.

Powerful 100W Fast Charging

The UGREEN X688 Uno delivers up to 100W maximum output, making it suitable for demanding USB-C devices. Therefore, you can use one charger for devices ranging from small mobile accessories to compatible laptops.

For users who carry a laptop and smartphone for work, this provides a convenient alternative to carrying several individual charging adapters.

Actual charging speeds depend on the connected device, cable, charging protocol, number of ports being used, and the power requirements of each device.

4-Port Multi-Device Charging

The X688 features a versatile 4-port configuration consisting of:

• 3 × USB-C ports
• 1 × USB-A port

This combination provides excellent flexibility for both newer and older USB devices. Moreover, multiple ports can be used simultaneously, allowing you to charge several devices from one power outlet.

For example, you can connect a USB-C laptop, smartphone, tablet, and another USB accessory without requiring four separate wall chargers.

Advanced GaN Technology

The UGREEN X688 100W Charger uses Gallium Nitride (GaN) technology to deliver high charging power from a relatively compact design.

GaN technology provides greater power efficiency compared with many traditional charger designs. As a result, UGREEN can provide substantial charging capability without requiring a large and bulky adapter.

Furthermore, the efficient design makes the X688 convenient for desks, workstations, bedside charging areas, and travel bags.

Intelligent Power Distribution

When several devices are connected, the charger automatically manages available power between the active ports. This helps provide appropriate charging power according to the requirements of connected devices.

Therefore, you can conveniently leave several devices connected without manually changing chargers. However, the maximum output available from an individual port may change when multiple ports are being used simultaneously.

UGREEN Uno Robot-Inspired Design

One of the standout characteristics of the UGREEN X688 Uno is its distinctive robot-inspired appearance. Unlike conventional chargers, the Uno series combines everyday charging functionality with a more playful and modern design.

The unique appearance makes the charger particularly suitable for modern office desks, home workstations, gaming setups, and technology-focused environments.

Charge Your Laptop and Mobile Devices

With its 100W maximum charging capability, the X688 is suitable for many compatible USB-C laptops. Therefore, it can potentially replace the standard charger for supported laptops while also providing additional ports for mobile devices.

It can be used with compatible MacBooks, Windows laptops, tablets, smartphones, and other USB-C electronics. However, the connected device must support USB-C charging and appropriate charging protocols to achieve higher charging speeds.

USB-C and USB-A Compatibility

The inclusion of both USB-C and USB-A means the X688 can accommodate a broad range of charging cables.

The three USB-C ports are ideal for modern devices that increasingly use USB-C connectivity. Meanwhile, the USB-A port remains useful for older cables and accessories.

Consequently, you can upgrade your main charger without immediately replacing every USB-A cable you already own.

Ideal for Home and Office Use

The UGREEN X688 Uno 100W GaN Charger can simplify charging areas where several electronic devices are used daily.

For example, instead of connecting separate adapters for a laptop, phone, tablet, and wireless accessories, you can connect them to one X688 charger. This helps reduce clutter around wall sockets and workstations.

Additionally, its compact construction makes it easy to move between different work areas when necessary.

Convenient for Travel

Carrying several charging adapters can take up valuable space when travelling. With four ports and up to 100W output, the X688 allows one charger to handle many everyday charging requirements.

As a result, it can be a practical option for business travellers, students, remote workers, and professionals who regularly carry several electronic devices.

Reliable Charging Protection

UGREEN incorporates intelligent charging management to help deliver stable power to connected devices. The charger is designed with multiple protection mechanisms for safer everyday operation.

These protections help manage common electrical risks such as excessive current, voltage, temperature, and short circuits. Therefore, users can conveniently charge compatible electronics at home, at work, or while travelling.
